Explain the photo of Snake with a 427 SOHC powered “digger”. This would have been about 1967. There’s a very interesting article in Engine Builder on Ed Pink. According to Pink, they were developing 2,500hp with the “SOHC” in 1967 when they began to have cracking problems. Ford was still supplying blocks to the Ford teams until 1970 when Ford began forcing teams to use the Boss 429 in Top Fuel and Funny Cars. The Boss didn’t fare well in the professional Fuel classes because Ford didn’t support the engine as they had the 427 SOHC. It’s a truly interesting article, but I have always been an admirer of Ed Pink.
